Ethics approval and consent to participate
: This study was performed under the international (Helsinki), Brazilian and UK research regulations and was approved by the Three Ethics Committee of Research: (i) University of Brasília (1.822.125), (ii) Instituto Gonçalo Muniz - Fiocruz (1.612.302) and (iii) London School of Hygiene and Tropical Medicine’s Research Committee (10580–1). We declare that the data used in this study we extracted from a de-identified dataset before its use. For this investigation, the Ministry of Health and the Ministry of Social Development formally shared raw data to CIDACS in order to perform data linkage, which in turn allowed this study to be carried out. Both Ministries have strict requirements to provide Centers with identified data for linkage, which were fulfilled by CIDACS. Researchers, nevertheless, receive de-identified data to work with, preserving anonimity of patients.
